NAME
SIZE - Returns the total number of elements in an array
SYNOPSIS
SIZE ([ARRAY=]array [,[DIM=]dim])
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
STANDARDS
Fortran 90
DESCRIPTION
The SIZE intrinsic function returns the extent of an array along a
specified dimension or the total number of elements in the array. It
accepts the following arguments:
array May be of any type. It must not be scalar. It must not be
a pointer that is disassociated or an allocatable array that
is not allocated. If array is an assumed-size array, dim
must be present with a value less than the rank of array.
dim Must be scalar and of type integer with a value in the range
1 <= dim <= n, where n is the rank of array.
SIZE is an inquiry function. The name of this intrinsic cannot be
passed as an argument.
RETURN VALUES
The result is a default integer scalar. The result has a value equal
to the extent of dimension dim of array or, if dim is absent, the
total number of elements of array.
EXAMPLES
The value of SIZE(A(2:5, -1:1), DIM=2) is 3. The value of SIZE(A(2:5,
-1:1)) is 12.
